A guide to replacing a gas water heater in North Delta's hillside homes, covering warning signs, code items, and what drives the timeline.

Quick answer
Most gas water heaters in North Delta last 10 to 15 years before rust, leaks, or reduced capacity signal it's time to replace. Because many homes here were built decades ago, a replacement often uncovers code items the original install didn't have, such as a missing drain pan or venting that needs updating for the new unit.

North Delta's housing stock leans older, particularly around Sunshine Hills and Scottsdale, where a lot of the split-level and raised-rancher homes still have mechanical rooms that haven't been substantially updated since the house was built. A water heater installed 12 or 15 years ago in one of these spaces is often approaching, or past, the point where replacement makes more sense than continued repair.
Secondary suites are common in the area too, and a tank sized for the original single household often struggles once a second kitchen and bathroom are drawing from it, shortening its effective service life even if the tank itself isn't old.
Because a lot of North Delta's tanks were originally installed decades ago, a replacement is often the first time the install gets checked against current code in years. Common items include a drain pan where the original install didn't have one, updated venting if the old chimney-vented setup doesn't suit the new unit, and confirming the gas line is sized for the new tank's input.
| Item | Why it comes up |
|---|---|
| Drain pan | Older installs sometimes predate the requirement |
| Venting material or routing | New unit's venting needs may differ from the original |
| Gas line sizing | Confirms it matches the replacement unit's BTU input |
| Seismic strapping | Some older installs are missing or have inadequate strapping |
| Combustion air | Finished basements can restrict air the mechanical room originally had |
The right size depends on how many people and bathrooms are drawing hot water, and whether there's a secondary suite involved. A single household with one or two bathrooms is usually fine on a standard tank; add a suite or a larger family, and it's worth discussing a bigger tank or a higher recovery rate so the household isn't running out of hot water during peak morning or evening use.
A straightforward tank-for-tank swap is usually done in a day. If venting or gas line upgrades are needed, or if the space has combustion air concerns to sort out, the job can take a bit longer. Costs vary with those factors, so it's a ballpark, not a quote, until the mechanical room has actually been assessed.
Safety note
If you ever smell gas, hear a hissing sound near the gas line, or notice soot, a yellow flickering burner flame, or a headache-and-nausea pattern that clears when you leave the house, get everyone out of the house first. Do not flip switches or search for the leak yourself. Once outside, call FortisBC at 1-800-663-9911 from a neighbour's phone or your cell before you go back in.
A minor leak at a fitting or a failed thermocouple can often be repaired. Rust from the tank body, visible corrosion, or a unit near the end of its expected service life usually means replacement is the better call.
Code requirements have evolved, and a replacement is often the point where an install gets brought up to current standards, including adding a drain pan if the space calls for one.
Sometimes, but not always. A licensed gas fitter checks whether the existing venting suits the new unit's requirements before reusing it.
A straightforward swap is usually a single day. Venting or gas line upgrades can add time.
Yes, a suite adds a second kitchen and bathroom drawing from the same tank, which often means discussing a larger tank or a different setup entirely.
That's typically sediment that's built up on the tank floor over the years, which insulates the burner from the water above it and makes the heater work harder.
